system_get_nodes_statistics

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

No annotations are provided, so the description carries the full behavioral burden, yet it only implies read-only via the 'GET' convention and the 'System Controller' tag. It says nothing about what is returned, aggregation scope, time window, freshness, or any side effects.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Is the description appropriately sized, front-loaded, and free of redundancy?

It is short and has no padding, but the brevity comes from under-specification rather than discipline, and the raw route line is not front-loaded as meaningful information for an agent.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

With no annotations, no output schema, and no explanation of return content, the definition leaves an agent unable to predict what 'nodes statistics' contains or how to interpret it, which is inadequate even for a simple read endpoint.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

The tool takes zero parameters, so there is nothing for the description to clarify beyond the schema; the baseline for a parameterless tool applies.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

The text is essentially a restatement of the tool name plus the raw HTTP route ('GET /api/system/stats/nodes') and a group tag. It gives no indication of what statistics are returned or how this differs from close siblings such as system_get_nodes_metrics, system_get_stats, or system_get_bandwidth_stats.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Does the description explain when to use this tool, when not to, or what alternatives exist?

There is no when-to-use guidance, no prerequisites, and no mention of any alternative. An agent cannot tell from this description when nodes statistics should be fetched instead of nodes metrics or the general stats endpoint.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
